Which suffix is used to refer to a condition of paralysis?

The suffix that is used to denote a condition of paralysis is "-plegia." This term originates from the Greek word "plēgē," meaning "stroke" or "blow," and is commonly used in medical terminology to describe various types of paralysis. For instance, "hemiplegia" refers to paralysis affecting one side of the body, while "quadriplegia" refers to paralysis of all four limbs. This suffix is specifically associated with motor function impairment, making it the correct choice for the condition of paralysis.

The other suffixes listed have different meanings that do not pertain to paralysis. "-pathy," for example, typically refers to disease or disorder, while "-dosis" relates to dosage or administration of medication. On the other hand, "-phobia" denotes an irrational fear of something. Understanding these distinctions is crucial for accurately interpreting medical terms.
